Tennis Ball Mortar
Posted by Cassie, August 23rd, 2009
Jonathan, Kelly Hanken, Paul Rowe, and I built a tennis ball mortar from three Pringles cans, and then went to Waterworks Park and shot a tennis ball from it.

Amazingly, the tennis ball mortar worked great on the first try! Unfortunately, we do not have a video for the first launch, but we do have a series of videos of our varying degrees of success. We found that we had to wait a little bit after shooting the tennis ball for the fuel and smoke to clear before attempting another launch. Otherwise there was too much fuel in the mortar, and the tennis ball did not launch.
